But Tuk's PCS in the Worlds FS was 57.24. She won the FS at Euros and was on the podium, whereas she was 10th at Worlds. Her PCS scores in the GP/GPF FSs ranged from 53-57 even when she skated well.

57 isn't that bad considering she skated in the 2nd warmup group, after Lafuente and McCorkell bombed, and Leonova, who the judges would have been willing to give a big PCS bump too, didn't skate well either. Had she been skating in the ultimate or penultimate warmup, I bet her PCS would have been a little higher, on par with Gold, Osmond, and Sotnikova. Start order usually effects PCS to a certain extent, I don't think Osmond was really overscored, or maybe just slightly, in the FS but skating in the final flight definitely helped her not fall farther in the standings than she did and helped her PCS too. Similarly, I thought her score in the SP could have been a little higher even (I thought she deserved to be above Kanako and Carolina honestly) but skating so early probably held back her marks a bit. Tuk's PCS aren't great, but with her technical side being as strong as it is, the PCS are not really going to prevent her from doing well as long as she jumps well. She more just does not have the luxury of making big mistakes and still getting huge scores like some others because her PCS aren't super high and do drop when she makes mistakes, unlike someone like Kiira, Carolina, Mao who have that cushion to fall back on.

Liza's PCS at WTT was 52 so she has a new low. She needs a help with PCS. From Skating Skills to Choreography to Performance. Osmond bombed badly and got 58. Look how horribly Liza is doing in PCS when she singles a jump and falls. It's atrociously awful in every way. For a brief second I thought Mae Berenice Maite beat her in PCS but Liza beat Maite by a point. If you are only beating Meite by a point and you are euro bronze medalist and winner of many free skates like in Euros and GPF you need help. This is awful and if she doesn't radically change every single thing about how the presents herself and skates she will be nowhere. Even against Maiete who will outdo her. This is among the worst things in skating right now her talent being ruined by an obviously judge repelling presentation as to where judges may prefer Maite.

Osmond didn't bomb that badly. She fell on a downgraded 3t and doubled the flip. That was a lot better than her Worlds FS, where she fell on two jumps. Osmond took a hit on PCS because she didn't skate with her usual zest. Only two judges gave her 8s in PCS, and we can guess which country one of them represented.

Liza gets low PCS scores because of her poor ice coverage; she has to nail all her jumps to get some 7s. IMO, Liza has a stamina problem and that limits her ice coverage. At WTT, her skating had an unfortunate lumbering quality which also is going to affect her PCS.

Exactly to the second paragraph. Either she needs to find new coaches who can help her or she is actually trying to improve and failing miserably. Judges are ready to start giving her 4's and 5's.
